Overexpression of Arabidopsis FLOWERING LOCUS T (FT) gene improves floral development in cassava (Manihot esculenta, Crantz)

Autor: Adeyemo, O. Sarah Chavarriaga Aguirre, Paul Tohme, Joseph M. Fregene, Martin A. Davis, Seth J. Setter, Tim L.

Cassava is a tropical storage-root crop that serves as a worldwide source of staple food for over 800 million people. Flowering is one of the most important breeding challenges in cassava because in most lines flowering is late and non-synchronized, and flower production is sparse. The FLOWERING ...

Journal Article 1999

Using microsatellites, isozymes and AFLPs to evaluate genetic diversity and redundancy in the cassava core collection and to assess the usefulness of DNA-BASED markers to maintain germplasm collections

Autor: Chavarriaga Aguirre, Paul Maya, M.M. Tohme, Joseph M. Duque E., Myriam Cristina Iglesias, C.A. Bonierbale, Merideth W. Kresovich, S Kochert, G

The cassava core collection was selected to represent, with minimum repetitiveness, the potential genetic diversity of the crop. The core (630 accessions) was chosen from the base collection (over 5500 accessions) on the basis of diversity of origin (country and geographic), morphology, isozyme p...

Transgenic plants of casssva (Manihot esculenta) with resistance to basta obtained by Agrobacterium-mediated transformation

Autor: Sarria, RA Torres Castro, Edgar Alonso Angel, F. Chavarriaga Aguirre, Paul Roca, William M.

Transgenic plants of cassava (Manihot esculenta) resistant to the herbicide Basta were obtained through Agrobacterium-mediated transformation. The plants also expressed the uidA gene and two were positive for PCR- and/or Southern-based detection of the nptII gene. Somatic-embryo-derived cotyledon...

Expression pattern conferred by a glutamic acid-rich protein gene promoter in field-grown transgenic cassava (Manihot esculenta Crantz)

Autor: Beltrán Giraldo, Jorge Alonso Prias, M Al-Babili, S. Ladino Franco, YJ López, D. Beyer, Peter Chavarriaga Aguirre, Paul Tohme, Joseph M.

A major constraint for incorporating new traits into cassava using biotechnology is the limited list of known/tested promoters that encourage the expression of transgenes in the cassava’s starchy roots. Based on a previous report on the glutamic-acid-rich protein Pt2L4, indicating a preferential ...

Genome mapping in cassava improvement: Challenges, achievements and opportunities

Autor: Fregene, Martin A. Okogbenin, Emmanuel Mba, C Angel, F. Suarez, MC Gutiérrez A., Janeth Patricia Chavarriaga Aguirre, Paul Roca, William M. Bonierbale, Merideth W. Tohme, Joseph M.

Breeding goals of yield increases, root quality improvement, and disease resistance in cassava are considerably slowed down by biological characteristics of the crop, which includes a long growth cycle, a heterozygous genetic background and a poor knowledge of the organization of crop diversity. ...
